PROBLEM TO BE SOLVED: To realize a noncontact DC motor in which the amount of a magnetic flux is made variable. SOLUTION: A first object 76 is provided with windings 85a, 85b, 86a, 86b, 87a, 87b. A second object 80 is provided with a core 105 and with permanent magnets 101, 102, 103, 104. The inductance of the second object 80 is made asymmetric with respect to the direct axis of magnetic poles generated by the respective permanent magnets 101 to 104. With this constitution, a force (a torque) and a reluctance force (a torque) in accordance with Fleming's left- hand rule can be fully utilized, and a high-efficiency motive-force generation device is realized. |
